Azure API 應用程序拋出請求大小限制錯誤

Question

我在 Azure API 應用程序中托管了一個示例 API，如https://epdpoc.azurewebsites.net/swagger/index.html這是基於 API.NET Core 5.0 的 Web API。 第二個參數 htmlText 作為查詢字符串傳遞。 查詢字符串值如下

<table border="0" width="100%">
<tr>
<td width ="50%">&nbsp;</td>
<td width = "50%">&nbsp;</td>
</tr>
<tr><td colspan=2><font face="Arial" size="2" >
{{SALUTATION}}<br>

通過如下設置請求大小，我有一個 Web.Config。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <!-- To customize the asp.net core module uncomment and edit the following section. 
  For more info see https://go.microsoft.com/fwlink/?linkid=838655 -->
  <system.webServer>
    <handlers>
      <remove name="aspNetCore" />
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath="%LAUNCHER_PATH%" arguments="%LAUNCHER_ARGS%" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="InProcess" />
    <security>
      <requestFiltering>
        <!-- This will handle requests up to 50MB -->
        ***<requestLimits maxAllowedContentLength="52428800" />***
      </requestFiltering>
    </security>
  </system.webServer>
</configuration>

我仍然收到來自 API App 的請求大小限制錯誤，如下所示。

驗證 applicationhost.config 或 web.config 文件中的 configuration/system.webServer/security/requestFiltering/requestLimits@maxQueryString 設置。

這里有什么線索嗎？ 有什么額外的設置要做嗎？

Answer 1

• 修復方法是更改​​ maxQueryString 設置（如果問題出在路徑中，則更改為 maxUrl）。 為此，請修改 web.config 文件中的安全元素：

   <system.webServer> <security> <requestFiltering> <requestLimits maxUrlLength="10999" maxQueryString="2097151"/> </requestFiltering> </security> </system.webServer>

• 在標簽中設置 maxQueryStringLength 屬性：

   <system.web> <httpRuntime maxUrlLength="10999" maxQueryStringLength="2097151" enable="true"/> </system.web>

maxQueryStringLength 默認為 2048。

注意：上面提到的只是一個例子。 根據您的要求設置值。
